NetBsd crashes on continuous ping. As per crash log the suspected line is a printf below.

(void)printf(" time=%.3f ms", triptime*1000.0); 
in pr_pack_sub() function

Seems like the %.3f is causing the crash. Please help if anybody faced this issue before.
>How-To-Repeat:
ping to any ip continuously for more than 12 hours
>Fix:
none
